The Nebulus brings guitarists high quality chorus, flanger and vibrato effects in a really compact 4.5 by 3.5 inch pedal. To increase the tone range even further 3 variations on each effect are available for a total of 9 tweak-able modes. All this flexibility is easy to access via a preset system capable of storing up to 8 different presets.
The chorus mode offers a lush and warm sounding chorus, a fluid and dreamy multi-chorus, and a unique tremolo'ed chorus. The flanger setting has a classic tape flange, a 70's negative feedback type flanger, and the elusive thru-zero flange. Lastly, but certainly not least, are the vibrato sub-modes which include a standard vibrato, a classic vibe sound, and a rotating speaker effect.
Each mode includes a special switch which allows the guitarist to really tweak crucial settings and it also offers some bonus features like the ability to add compression to vibrato mode, for example. For further fine tuning, a tone switch is available offering warm, clean, and bright voicings to the effect.
This true bypass pedal offers the uncompromising sound quality that guitarists have learned to expect from Empress pedals in an incredibly small box. With chorus, flanger and vibrato all only one touch away, this pedal is an incredible value.
